- ELECTROMAGNETIC TOY ENGINE.

Specification of Letters Patent.

Patented March 24, 1908.

Application filed De ember 18, 1907. Serial No. 407,000.

Engines; and we do declare the following to be a full, clear, and exact description of the invention, reference being bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to operative toys, and it has reference particularly to electromagnetic toy engines.

, Objects of the invention'are to provide a simple and inexpensive toy engine to resemble or imitate practical steam engines or explosive engines, a further object bein to provide a toy of the above-mentioned c iaracter that may be not onl amusing but which may be utilized for ifiivin toy machines of various kinds, a still furt or object being to provide an electro-magnetictoy engine that ma be constructed at the minimum cost and e durable and economical in use.

The invention consists in an improved electro-magnetic engine comprising an upright frame, a pair of electro-ma net cores depending from the topof the rame and having suitable windings, a main shaft mounted in the frame, an armature wheel secured to the shaft and having armatures projecting from opposite sides thereof to be carried thereby between the magnet cores, the wheel being provided with pins atone side thereof to engage either one of two adjustable contact fingers for making and breaking the electric circuit, the iingersbeing controlled by a reverse lever, so that the engine ma be adjusted to operate in either forwar or backward directions. And the invention consists further in the parts and combinations and arrangements of parts as hereinafter particularly described and defined in the claims appended hereto.

Referrin to the drawings Figure 1 is an elevation 0 one side of the lmproved engine; Fig. 2, an elevation of another side thereof;

Fig. 3, a vertical sectional view ap )roximately on the line A A in Fig. 1; and, ig. 4, a horizontal sectional view approximately on the line B B in Fig. 2.

. Similar reference characters inthe different figures of the drawings designate like elements or features of construction.

In a practical embodiment of the invention, a suitable base plate a is provided that is adapted to lie horizontally, the base being preferably metallic, and on the top thereof two metallic upright frame members hand 1) portions of the members having each a screwflanged ends e and e that are connected by a suitable distance and considerably beyond the lower ends ofthe windings. 'lhe windings of the two cores are connected by a circuit wire j, the winding it being connected b a wire k to the frame member I), and the win( ing h being connected by a wire I to a binding post m that is mounted on the base a. The frame members are-provided with a pair horizontal plane between the base a and the lowerends of the core extensions, the bearings being preferably screwed into the frame members and locked by means of locking nuts, the inner ends of the bearings being suitabl adapted to rotatively support a main 5 aft 0 that has its ends journaled in the bearings, so that the main shaft is arranged horizontall An armature wheel p is suitably secured to the. main shaft near the middle ortion thereof, and has a suitable humber'n armatures q projecting from one side thereof, and a suite le number of similar armatures projecting from the opposite side thereo the wheel being of suitable diameter, so as to extend between the two core extensions t and 'i, and the armatures are so arranged on the wheel that they may be carried between the core extensions and at suitable distances therefrom to be attracted by the energized cores. In this manner the magnetic power is applied to both sides of the wheel so that the wheel will run steadily on its bearings and not wabble as would be the case in cheap toy construction if the power were applied at one side only of the wheel intermittently, and

are suitably secured thereto, the uppermost olt c or 0 connected thereto. A yoke d has the screw-bolts to the frame members, theof bearings n and n that are arranged in a ,gine, a pinion 7 is suita the bearings not close fitting. A suitable bearing 8 is mounted on the base a and an opposite bearing s; is mounted in the lower ortion of the frame member 1), preferably being screwed into the frame so as to be adjustable and held by a lock-nut. it rock shaft t is journaled in the bearings s and s and has a connector late a secured thereto but electrically insu ated therefrom by a layer of insulating material a, the plate being curved and having two contact fingers U and 'v' fixedly mounted thereon, so that either finger may be moved to the circular path of the pins 1" to form contact therewith, the rock shaft being provided with a reverse lever 10 to be latched in connection with a suitable latch bar at mounted on the memher I). A contact plate 7 normally rests on the plate a and is secured to a binding est 2 and insulated from the base a by insuihting material 2 or otherwise as may be desired. Circuit wires 5 and 6 are connected to the binding posts 2 and m respectively, to be connected to the two elements of a battery for energizing the electro-magnets.

In order to transmit ower from the enlily attached to the main shaft 0 and an axle S is mounted on the frame member 5 and rotatively supports a gear wheel 9 that engages the pinion 7 and has a grooved ulley 10 attached thereto, so

that a drive be t may be driven by the pulley to drive other toys.

In practical use, the direction of movement of the engine may be determined by means of the reverse lever to which may be shifted so as to move either the finger v or the finger v to the path of movement of the pins 1. In the resent case four armatures are on either si e of the wheel p and there are four pins 7". When either armature is near the core extension and advancing thereto, contact will be made between a pin rand the finger e or v, the contact being broken when the armature arrives at the core, and the momentum of the wheel will carry the other armatures forward in succession, as will be understood. The late y permits the rock shaft t to move free y with the plate a sliding in contact with the plate '1], so as to form electrical connection. Other results of the operation of the engine will be readily understood from the foregoing detail descri tion of construction.

aving thus described the invention, what is claimed as new is- 1. In an electro-magnetic toy engine, the

""combination' oftwo upright frame members havin each a journal bearing, a yoke attache to portions of the frame members,

two wound electro-magnet cores attached to the yoke and extending therefrom, the cores havmg extensions )rojecting beyond the windin s thereof, a shaft mounted rotatively in the ournal bearings, an armature-wheel secured to the shaft and extending between the extensions of the two cores and having a plurality of armatures on opposite sides thereof to be carried thereby between opposing sides of the two core-extensions.

2. In an electro-magnctic toy engine, the combination of a base, two upright frame members having each a bearing that is adjustable toward or from the other in horizontal direction, a shaft mounted rotatively on the bearings, a yoke secured to the frame members above the shaft, two armature cores attached to the under side of the yoke and extending towards the shaft, an arma ture-wheel secured to the shaft and carrying arn'iatures on the two sides thereof between the lower ends of the cores, ins projecting from a side of the armaturc-wlieel, a contactfinger mounted in the path of the pins, a binding post on the base in connection with the finger, and windings on the cores connected with the frame mci'nbers.

3. In an electro-magnctic toy engine, the combination of a base, two upright frame members on the base, two binding posts on the base, a shaft mounted rotatively between the frame members above the base, a yoke attached to the uppermost portions of the frame members above the shaft, two magnet cores attached to the under side of the yoke and extending downward toward the shaft, an armature-wheel secured to the shaft and carrying armatures on the two sides thereof between the opposing sides of the lower ends of the cores, pins on one side of the armature-wheel, a bearing mounted on the base, a bearing mounted on one of the frame members, a rock shaft mounted on the two bearings and provided with a reverse-lever, a connector-plate secured on the rock shaft and insulated therefrom, a contact-plate in engagement with the connector-plate and having connection with one of the binding posts, two contact fingers on the connectorplate and movable to or from the path of the pins, windings on the cores connected together and to a frame member and also to the other binding post, a pinion secured to the shaft, an axle mounted on one of the frame members, a gear wheel on the axle and engaging the inion, and a pulley carried by the gear wheel:
